Central Contra Costa Sanitary District March 3, 2015 TO: REAL ESTATE, ENVIRONMENTAL & PLANNING COMMITTEE VIA: ROGER BAILEY, GENERAL MANAGER AK JEAN -MARC PETIT, DIRECTOR OF ENGIN ERING he DANEA GEMMELL, ENVIRONMENTAL SERVICES DIVISION MANAGER a� NATHAN HODGES, PROVISIONAL SENIOR ENGINEERM FROM: MELODY LABELLA, PROVISIONAL ASSOCIATE ENGINEER � SUBJECT: PROPOSED SCOPE ELEMENTS FOR REQUEST FOR PROPOSAL ON A STUDY OF POTENTIAL OPPORTUNITIES FOR WHOLESALING RECYCLED WATER The Real Estate, Environmental & Planning Committee has requested that staff issue a request for proposal (RFP) to evaluate potential opportunities to wholesale Central Contra Costa Sanitary District's (CCCSD) recycled water inside and outside of CCCSD's service area boundaries, with the ultimate goal of reducing, or even possibly eliminating CCCSD's treated wastewater discharge to Suisun Bay during dry weather season. The results of this study will be shared and coordinated with the upcoming Comprehensive Wastewater Master Plan. The following proposed scope elements are presented for your consideration: Task 1: Data Collection and Review Consultant will review past studies to ensure no duplication of efforts. Those studies will include: 1. 1999 Bay Area Regional Water Recycling Program (BARWRP) Master Plan 2. 2000 CCCSD Recycled Water Master Plan (RMC) 3. 2013 CCCSD Update of Refinery Recycled Water Costs Report (HDR) 4. 2013 CCCSD- Contra Costa Water District (CCWD) -US Bureau of Reclamation Recycled Water Project Yield Study (RMC -MBK) 5. 2014 TM on Bringing CCCSD 42 -inch Industrial Pipeline Back into Service (RMC) 6. 2014 Refinery Recycled Water Project Feasibility Study (RMC) Task 2: Market Assessment Consultant will utilize existing information, coupled with an assessment of any updated Northern California water supply needs, to determine if a market exists for CCCSD's REEP Committee March 3, 2015 Page 2 of 2 recycled water; all recycled water qualities will be considered. A broad list of potential recycled water users will be developed. Users could include water agencies, irrigation districts, etc. Users could receive CCCSD's recycled water directly or through water transfer /exchange as a result of implementation of the full 20 MGD Contra Costa County Refinery Recycled Water Project, which could free up approximately 10 MGD of CCWD raw water supply. Task 3: Development of Alternatives Consultant will develop up to five (5) conceptual recycled water wholesaling opportunities to meet the overall objective of this project. For each alternative, water quality requirements, level of treatment, flow delivery schemes, and pumping and storage requirements will be defined. Consultant will identify preliminary regulatory issues, potential institutional issues, needs for agency partnerships, and needs for stakeholder and public support. Task 4: Evaluation of Alternatives Consultant will identify potential benefits to CCCSD and other public and private entities affected by the recycled water alternatives defined in Task 3. Consultant will monetize the value of benefits (i.e. replacement of potable water supplies) for the recycled water alternatives to the greatest extent possible. Consultant will develop life cycle cost estimates to implement and operate the recycled water alternatives. An economic analysis will be conducted comparing costs versus benefits of the recycled water alternatives. Based on this analysis and the regulatory, institutional and other issues identified in Task 3, the advantages and disadvantages of recycled water alternatives will be compared and documented. Task 5: Staff /Board Committee /Board Workshops Consultant will facilitate two (2) workshops with CCCSD's staff, Board Committee or full Board of Directors during the course of the study to obtain input and feedback. Task 6: Project Report Consultant will prepare a summary report describing the development and evaluation of alternatives, and findings and conclusions. Staff anticipates the consultant level of effort for this Study of Potential Opportunities for Wholesaling Recycled Water to be $75,000 - $95,000. We look forward to discussing these proposed elements with you at the March 10, 2015, REEP Committee meeting. We anticipate that this work will begin this summer and be completed by the end of the calendar year.
